BRACKET Eon THREAD CLEANERS.

Application filed June so, 1927. Serial no. 202,505.

This invention relates to improvements in thread cleaning devices, and has partlcular reference to brackets therefor especially adapted for use with thread clean ng plates such as disclosed and claimed in our former Patent No. 1,625,352, dated April 19, 1927.

An object of the present invention is to provide an improved bracket for support ng cleaner plates, which is er simple, practical and inexpensive construction and which is so made that it can be applied to various types of apparatus and machines" employed in winding threads and positioned relative thereto in such a manner asto effect the highest degree ofefliciency in the thread cleaning operation. 7 I I r Another object is to facilitate the mount ing of cleaning plates in the bracket so that the same will be properly positioned therein with respect to each other and to the thread being cleaned, and iiiaiii tained in such position during the cleaning operation;

s more clearly from-the following detail deillustratin the scription, when taken inconnectionwith the accompanying drawings, 7 whlch llustrate preferred embodiments of the inventive idea. In the drawings 7 p I Figure 1 is a fragmentaryelevation, part ly in section, of one form of the invention,

Figure 6 is a section on the line 66 of Figure 4; p p

Figure 7 is a view similar to Figure 5, illustrating the manner in which the bracket is mounted on a metal or wooden bar;

Figure 8 is a section on the line 8 -8 01' Figure 7;

Figure 9 isa View similar to Figure 5,

to an angle iron; and v Figure 10 is a section on the line 1()1O of Figure 9. p "H i The brackets or the present invention have been designed particularly with theend in application er the bracket view of making the same applicable to varialso be applied to rcdrawers- In said figures the numeral 11 indicates a swift upon which the skein of thread 12 to be 'cleaned is wound, said thread being fed from said swift over the usual traverse bar 13 which reciprocates in front of a plurality of bobbins, one of I which is indicated at 14 and driven bymeans ot the wheel 15 rotatably mounted on a com- I I mon driving shaft 16. i The above and other objects will appear,

attached to the traverse bar, as nearly aspos siblej in a directline belowsaid bar to-avoid tilting thereof which might otherwise occur andwhich'would result in a defective operation of said bar. The arrangement of the bracket aslshown also" permits of the thread passing between the cleaner plates at unpreper angle which will produce the most efficient operation and cleaningof the thread.

The bracket shown comprises a central substantially rectangular plate supporting one surfaceofwliich is in a plane with one wall ofthc opening 18, so that theportions or the plates 19 which project from said side of the-portion 17 will abut against said surface of theextensi'on 20. To limit the movement portion 17 having an opening lS extending l ll) V Figure 3.

of the-plates 19 as they are being inserted into the portion 17 from the side thereof opposite the extension 20 and to thereby properly position said plates in the bracket, said extension 20 is provided at its free extremity with a laterally projecting stop 21 having angularly disposed surfaces against which the angular guide surfaces of the plates 19 engage, as clearly shown in. After the plates have been so inserted into the bracket they are fixed in" their operative positions by means of a screw 23 countersunk in one face of the portionl'? and provided in its outer endwith a key opening 24; into which a suitable key may be fitted to thread the inner end of the screw into binding engagement with the adjacent edge of one of the cleaner plates 19. This screw not only enables the'plates to be easily and rapidly secured in their operative positions, but also allowsthem to be quickly detached from the bracket and their positions changed or replaced by other plates in accordance with the invention set forth in the aforementioned patent. v

Extending at rightangles from one face of the portion 17 and extension 20 is a supporting arm 25 which maybetapered as shown in Figure '2, and this arm is provided adjacent its free extremity with an opening for receiving the screw 26 of a thread'guide 27 having a central thread receiving slot28. the entrance end of which is overlapped by the two oppositely projecting retaining hooks 29. Although it is preferable to use this kind of a guide, it will be understood that other types may be also employed. A nut 30 may be threaded on the screw 26 and engaged with the arm 25 to retain the guide in its operative position. It is desirable that the arm 25 be of such a length that the guide 27 is spaced from the cleaning plates a suificient distance to enable the proper manipulation of the thread and the removal of waste, dirt, etc. from said plates. The proper spacing of the guide 27 from the cleaning plates 19 will also dispose said guide at such a distance from the skein offsilk being unwound as to effect a most eflicient operation and reduce as much as possible 7 the friction on the thread 12.

011 the face of the portion 17 oposite that from which the arm 25 extends, there ,is formed a second suporting arm 31: offset relative to the portion '17 and provided with an upper bearing surface which abutsagainst the lower edge of the'traversebar 13 when l the bracket is suspended therefrom'in proper position. One edgeof the arm 81is provided with they lugs 32 which engage back of the traverse bar as shown in Figure 1. Said arm l is further provided thereinwith a slot 33 through which maybe extended a screw :34 for the purpose, of

- securing the bracket to the traverse bar, said the slot" permitting of limited longitudinal adjustment of the bracket'relative to said bar.

An additional thread guide 35 is removably mounted upon the top edge of the traverseba r, 13 and held in position thereon by the springs 36, the eye of said guide being in alignment with the slot formed between the inner edges of the plates 19 and also in alignment with the slot or eye 28 of s andarin 25 of the bracket are precisely the same asthatabove described; Instead of the offset" arm 31, the present embodiment is provided withtan arm 37 of the same formation as the arm 25 and extending directly from theface of the portion 17 opposite that carrying said arm 25. Both ofthe arms 25 and 37'may, in this instance, carry the thread guides 27, the eyes of which are aligned with the slots formed by the plates l9; lVith this form of bracket wherein the extension 20 and thetarm 25 are again at right angles toeach other, the device is adaptedto be mounted upon various shaped members on different types of machines. Asillustrated in Figures 4; to 6, the bracket is mounted imposition upon a rod 38 by employing a block 39 secured to said rod by the screw. lOv and fitting into the angle formed by the exten- V In Figures? and8, the bracket is illustrated as being mountedupon a rectangular bar {12,which may be of metalor wood and which also fits into 'theangle formedbythe parts 20 and 25, the bracket being secured in positionon the bar by thescrew 43.

In Another manner ofmounting this universally adaptable bracket is shownoin Figures 9 and 10, wherein the bracket is attached to an angle iron 4413mm screw 45. Thus it will be seen that the brackets shown in the, different figures of the drawings are, by reason of'their peculiar novel'constru'ction, capable of being mounted uponseveraldifferent types of machines and members thereof, and further that the bracket provides a simple and highly efficient means for supporting and retainingthe thread cleaning thread" being cleaned;
